HYDROTHERMAL SYNTHESIS OF SPHERE-LIKE ZINC COBALTITE FOR ENERGY STORAGE DEVICES

The electrochemical performance of zinc cobaltite–based nano/micromaterial depends on its shape and morphology. Here we report on the electrochemical performance of zinc cobaltite (ZnCo O ) material synthesized via a facile 2 4 hydrothermal method. The synthesized material was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) analysis. It was found to be a single-phase zinc cobaltite material with a cubic spinel crystal structure. The electrochemical performance of the synthesized zinc cobaltite microstructure material was evaluated by cyclic voltammetry, cyclic chronopotentiometry and electrochemical impedance -1 -1 spectroscopy. The zinc cobaltite microspheres material displayed a high specific capacitance of 600.37 F g at a current density of 1 A g . Such electrochemical performance may qualify the zinc cobaltite microspheres material as a potential electroactive material in supercapacitors.

Burst abdomen-A preventable morbidity.

A burst abdomen is considered present, when intestine, omentum or other viscera's were seen in the abdominal wound following obstetric surgery. In our country no study found, but observational incidence in the tertiary hospital varies between 0.2-3%. It occurs mostly between the sixth and eight day after operation. Factors relating to the incidence of burst abdomen are suture, closure, incision, coughing, vomiting, distension, obesity, jaundice, malignancy, diabetes mellitus, hypoproteinaemia, anaemia, immuno-compromised patients and wound infection. During the period of February 2001 to February 2006 four cases of burst abdomen were managed in cooperation with team of surgery department. In these cases wound were closed by "May/Mary closure". Abdominal wound dehiscence remains a major cause of morbidity following any laparotomy whether elective or emergency. We should correct the primary risk factors for wound dehiscence. Transverse incisions are generally considered to dehiscence much less than the vertical incision. The suture should have excellent handling and knotting. Its prevention is important to reduce postoperative morbidity, mortality and increased cost of care both in terms of increased hospital stay and treatment of the complication.

Endometriosis association research center.

Endometriosis, the presence of endometrial tissue outside the uterus, is a progressive, estrogen-dependent disease and occurs nearly exclusively in menstruating women of reproductive age. Pain syndrome, however, represents the major clinical problem of this disease, manifested as dysmenorrhea, pelvic pain, lower abdominal pain, and dyspareunia. About 32 literatures are reviewed in recent advancement for diagnosis of endometriosis. The magnifications of its managements are understood. In outdoor, the management is only depending on clinical findings and on some non invasive procedures without any definitive diagnosis. So, research activities should be done on the basis of recent advancement of endometriosis.

Serum total protein, albumin and A/G ratio in different grades of protein energy malnutrition.

The serum total protein, albumin and serum A/G ratio was studied on 20 healthy children and 30 children suffering from protein energy malnutrition of different grade such as grade-I grade-II and grade-III. Serum total protein and albumin levels in grade-I grade-II and grade-III PEM were significantly lowers than control. Serum total protein between different grades of PEM was changed but not significantly. Serum A/G ratio of grade-1 & grade-II PEM were high than that of control, but not significantly. Serum A/G ratio of grade I and grade II PEM were higher than that of control, but not significantly. But in grade-III PEM this values were significantly higher than that of control. When comparison were done within the different grades of PEM, it was found that their A/G ratio were changed but not significantly.

A comparative study of body iron status and lipid profile in acute myocardial infarction patients.

This study was carried out to evaluate the relationship between body iron status and lipid profile in hospital admitted clinically diagnosed AMI patients considering the concept that there is a potential association between body iron status and coronary heart disease (CHD). Total 80 subjects were selected, of which 40 were healthy adults and 40 were AMI patients. Fasting blood samples were collected from healthy adults. Blood samples of AMI patients were collected within 24 hours of the attack of myocardial infarction. Body iron status was measured in term of 3 variables serum total iron concentration, TIBC and transferrin saturation. Lipid profile variables measure were total cholesterol, triglyceride, LDL-cholesterol and HDL-cholesterol. No correlation was found between serum iron and the variables of lipid profile. TIBC was found to maintain negative correlation with total cholesterol, triglyceride and LDL-cholesterol but positive correlation with HDL-cholesterol. Transferrin saturation was found to maintain strongly positive correlation with total cholesterol, triglyceride and LDL-cholesterol but strongly negative correlation with HDL-cholesterol. This correlation of TIBC and transferrin saturation with lipid profile supports the hypothesis that there is a potential association between body iron status and coronary heart disease.

Management of severe malnutrition and diarrhea.

Children with severe malnutrition and diarrhea have high mortality rates that have been attributed to faulty case-management. Health workers are often unaware of the unique treatment requirements of severely malnourished children resulting in improper case-management. Moreover, the lack of prescriptive guidelines promotes the exercise of discretion in case-management that is often detrimental. Appropriate feeding from the start of treatment, routine micronutrient supplementation, broad-spectrum antibiotic therapy, less use of intravenous fluids for rehydration, and careful management of complications are factors that can reduce death, morbidity and cost of treating children with severe malnutrition and acute illnesses including diarrhea. In this paper is discussed a standardized protocol based upon the above mentioned factors for the management of severely malnourished children with acute illnesses including diarrhea. Implementation of the protocol resulted in a 47% reduction in mortality in these children.
